Secure Seal™ is a brand name awarded to a special EPCO line of #10 White Wove envelopes, because of their unique ability to expand to accommodate multiple inserts. With a full .001" of gum on the flap, Secure Seal™ envelopes have been proven to carry up to twice as many inserts as conventional style #10’s, without gluing to the inserts.

If you hand-insert multiple forms, we urge you to compare Secure Seal™ to the envelopes you’ve been using. Your mail room employees and recipients will appreciate the increased convenience, and you’ll experience less waste.
